Thanks first for your answer, now is something clearer (or maybe not), in fact here the two outputs:
pacman -Qqm
autoupgrade
brother-hl3152cdw
ceph-libs
cmst
downgrade
gconf
ipw2100-fw
ipw2200-fw
paru
timeshift-autosnap
yandex-browser-beta
and...
pacman -Qqem
autoupgrade
brother-hl3152cdw
cmst
downgrade
ipw2100-fw
ipw2200-fw
paru
yandex-browser-beta
if your commands are right, apparently, `ceph-libs`, `ckb-next`, `gconf` & `timeshift-autosnap` are NOT AUR-Packages, but, searching with paru are the results different:
1 aur/ceph-libs 17.2.5-1 [+3 ~1.70] [Installed: 15.2.14-6]
Distributed, fault-tolerant storage platform delivering object, block, and file system
2 aur/ckb-next 0.5.0-2 [+47 ~1.68] [Installed]
Corsair Keyboard and Mouse Input Driver, release version
1 universe/ckb-next 0.4.4-4 [1.11MiB 2.82MiB] [Installed: 0.5.0-2]
Corsair Keyboard and Mouse Input Driver, release version
1 aur/gconf 3.2.6+11+g07808097-10 [+109 ~6.31] [Installed]
An obsolete configuration database system
1 aur/timeshift-autosnap 0.9-1 [+44 ~3.08] [Installed]
Timeshift auto-snapshot script which runs before package upgrade using Pacman hook.
I install intentionally: `brother-hl3152cdw`, `ckb-next`, `cmst`, `downgrade`, `paru`, `timeshift-autosnap` & `yandex-browser-beta`... hence, something can't be correct.
I use `openrc` and this is well supported (thanks for your Link) and works also perfect without any mofication.
The topic is: I cannot let issue a file containing only AUR packages I can install with `paru -S --needed --noconfirm <packages-names>` because paru could pick ckb-next from repository with ver. 4 and not 5 like pacman done as `chb-next-openrc` was in the repository.
The problem is: The package-developers make a good job that don't require any manual adjustment from user (apart to add and start it in openrc), but... still required some "attentions" to avoid install the wrong package.
The general recommendation is: "If you can, don't use AUR-Packages" and now!? I have an AUR-Package installed with an AUR-Helper and the System "pacman" claim to be a repo-package. The user respecting those guidelines install ckb-next with pacman and this version don't work.
Sorry, I cannot explain more simple than I have just done.
